7. Tournament Rules

  • Modified FIDE-rules apply.
  • Forfeit time is 30 minutes without prior notice, 60 minutes if we are notified.
    A player will be awarded a forfeit win against any opponent who doesn't show up according to the prescribed rules, and every effort will be made to find that player an extra game.

8. FAQ

  • What do the time controls mean?
    Time controls tell you how much time you have for each game.
    G120;d5 means game in 120 minutes (aka 2 hours) with a 5-second delay on each move. This means you get 120 minutes, your opponent gets 120 minutes, and at each move the clock counts down from 5 to 0 before the player's time starts. If a player doesn't use up the whole 5 seconds, the remainder of that time is lost.

  • How many games/rounds?
    The 7SS before the time control means
    it is a Swiss System tournament with seven rounds, or seven games, that a player can play in the tournament. The tournaments are never elimination, so win or lose, you can stay in the tournament.
